Survey Methodology

To ensure all Maryland citizens are represented, the Goucher Poll is conducted using
random digit dialing (RDD) of a stratified random sample using landline and cellular
telephone numbers. The sample of telephone numbers for the survey is obtained from
Survey Sampling International, LLC (http://www.surveysampling.com/).

The Goucher Poll typically conducts surveys from 12pm to 9pm on Sunday and from 5pm
to 9pm on Monday through Thursday. The Goucher Poll uses Voxco Computer Assisted Telephone
Interviewing (CATI) software to administer its surveys. Interviews are conducted by
a staff of professionally trained, paid student interviewers.

Interviewers attempted to reach respondents with working phone numbers a maximum of
five times. Only Maryland adults-residents aged 18 years or older-were eligible to
participate. Interviews were not conducted with adults who were reached at business
or work numbers. For each landline number reached, one adult from that household was
selected on the basis of being the oldest or youngest adult in that residence. Interviews
are conducted on landlines and cellular phones.
